New: added support for continuous load progress notification.

Previously, Cappuccino only called OBJJ_PROGRESS_CALLBACK when an executable or image sprite file was finished loading. Only a slow connection, this would result in long periods with no visible progress.

Now OBJJ_PROGRESS_CALLBACK is called continuously during download via the XHR progress event. All supported browsers except IE 9 support this event.
New: new index.html with loading progress by default.

Previously, the index[-debug].html in the default capp templates did not include a loading progress function. We just had the plain spinner, which gave no visible sign of progress.

Now the capp templates include a progress function and a nice iOS7-ish progress thermometer	is displayed during loading (except when run directly from source). 'jake debug' and 'jake release' will now generate the application/image sizes needed to display loading progress. The old spinner.gif has been removed.

In addition, the message displayed when JavaScript is unavailable has been simplified and shows a link to www.enable-javascript.com instead of the missing link to our old site.
